Is it possible to get the total number of items defined by an enum at runtime?
While it's pretty much the same question as this one, that question relates to C#, and as far as I can tell, the method provided there won't work in Objective-C.

An enum
is a plain-old-C type, therefore it provides no dynamic runtime information.
One alternative is to use the last element of an enum to indicate the count:
typedef enum {
Red,
Green,
Blue,
numColors
} Color;
